" DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 310,977, dated January 20, 1885.

Application filed October 21, 1884. (No model.)

To all whom it may concern:

Be it known that I, CHARLES BELLMANN, of Barton, in the county of Washington,and in the State of Wisconsin, haveinvented certain new and useful Improvements in Three-Horse Equalizers; and I do hereby declare that the lollowing is a full, clear, and exact description thereof.

My invention relates to improvements in draft-equalizers, and will be fully described hereinafter.

The'drawing represents a top plan view of a draft-equalizer embodying my invention.

A is the whiffletree, which is pivoted in any suitable manner, asat a, to the vehicle-tongue B. CD are bell-crank levers working one on each end of the whiffletree on their respective pivoting-pins c d. The short arm of the cranklever O is perforated, as at c c, to receive the hooking end 6 ofthe adjustable rod E, the opposite end of which, 0, is adapted to fit loosely in either one of the perforations d d d made in the long arm of the lever D. The free end of' the short arm in lever G andthat of thelong arm in lever I) are provided with the respective extensions 0 D, to which are attached in any of the usual modes the single-tree F and the double-tree G, thislatter having attached thereto, one at each end, the single-trees F and F From the above description and the drawing it will be readily understood that the horse hitched to the single-tree F will be enabled. through the interposition of the levers G and D and the adjustable rod E, to keep abreast of the horses hitched to the opposite end of the whiffletree. The adjustments of the rod E in either one of the perforations d d and do -l will permit of hitching to the vehicle horses of unequal drafting capacity, the pulling ahead 0 of the one and the dragging behind of the others being entirely avoided in the simplest manner possible.

This device is represented in the drawing and described as applied to a three-horse team; but it is obvious that the same may be used with a two-horse team of unequal power or with five horses or more, according to the needs of the case. A change only in the arrangement and number of the hitching-trees will be necessary.

Having thus described my invention.what I claim as new, and desire to secure by Letters Patent, isl 1.. In a draft-equalizer, awhiffletree having pivoted to its opposite ends the crank-levers O D, the short arm of the former and the long arm of the latter being adapted to be loosely connected at various points of their length by means of an adjustable rod, whereby the un- 6, equal draft exerted on single-trees attached to the opposite arms of the respective levers will be evenly balanced, substantially as set forth.

2. In a draft-equalizer, the combination, with the tongue B, of the whiffletree A, cranklevers O D, respectively perforated at o c and d cl, adjustable rod E, double-tree G, and sin gle-trees F, F, and F, substantially as shown and described, and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukeein the county of Milwaukee and State of Wisconsin, in the presence of two witnesses.
